Vibration Technology

Information on Vibration Technology

Today the reduction of vibration emission and vibration immission play an important part in the operation of plant and machinery, etc. The constant improvement in machine performance over recent years has generally been accompanied by increased speeds and cutting rates, as well as an increase in impact power in the field of forming. This means an increase in the vibrations transmitted to the surroundings, which must be efficiently controlled.

The basic principle of vibration isolation
The objective of using insulating mechanisms for machine mounting is the reduction of pulsating (repetitive), or sinusoidal vibrations. The task is to keep the motion (amplitude) of the flexibly mounted machine within permissible limits for operation. The vibration insulators selected must have sufficient dampening capacity!

Matching up the important factors

Insulation of sinusoidal vibrations The efficiency of vibration insulation depends to a large extent on the relationship between the machine speed/stroke rate and the natural vibration frequency of the insulator (matching ratio). In general, it can be said that the lower the natural vibration frequency of the insulator, i.e. the greater the ratio between forcing frequency and natural frequency, the greater the efficiency of the insulator. The diagram below shows that vibration insulation does not take effect until the
matching ratio ( η) is greater than √2.
